Using the bookstore model, queryDataNodes returns nothing in this case:

cpsQueryService.queryDataNodes(FUNCTIONAL_TEST_DATASPACE, BOOKSTORE_ANCHOR, '/bookstore/categories[@code=1]', INCLUDE_ALL_DESCENDANTS)

(regardless of fetchDescendantsOption.)

Meanwhile, getDataNodes returns correct data:

cpsDataService.getDataNodes(FUNCTIONAL_TEST_DATASPACE, BOOKSTORE_ANCHOR, '/bookstore/categories[@code=1]', INCLUDE_ALL_DESCENDANTS)

returns:

• /bookstore/categories[@code='1']
  • /bookstore/categories[@code='1']/books[@title='Matilda']
  • /bookstore/categories[@code='1']/books[@title='The Gruffalo']

Difference of integer/string leaf value

In the bookstore.yang model, categories key is defined as "code" attribute:

list categories {
    key "code";
    leaf code {
        type string;
    }
...

So using a string leaf value returns correct results:

/bookstore/categories[@code="1"]

while this returns nothing:

/bookstore/categories[@code=1]

However, both these queries return same results:

• /bookstore/categories[@code=1]/books[@title="Matilda"]

• /bookstore/categories[@code="1"]/books[@title="Matilda"]

Not to mention getDataNodes returns same results for these:

• /bookstore/categories[@code=1]

• /bookstore/categories[@code="1"]
